12 Claims.

This invention relates to record controlled machines and more particularly to that type of machine which has become known in the art as a collator, a representative commercial form oi which is disclosed in Patent No. 2,379,828.

In this type of machine, provisions are made for feeding perforated record cards and comparing them and distributing them in accordance with comparisons made of certain data which ordinarily is recorded in the cards by means of perforations. The machine disclosed in this patent compares the records and distributes them in various ways in accordance with numbers recorded in the records by means of perforations and the records themselves consist of a very commonly used form of record card.

The primary object of the present invention is to provide an improved comparing mechanism for a machine of the above type which is capable of comparing records alphabetically as well as numerically.

Another object is to provide a comparing mechanism which enables records to be compared alphabetically without resorting to the expedient of using two columns on the record card for each character recorded.

An object is to provide a comparing mechanism which requires only a very simple alteration in the structure of the machine shown in the above patent to enable records to be compared alphabetically. y

An object is to provide a record comparing mechanism which enables records to be compared alphabetically without resorting to the expedient of sacricing record capacity when the alphabetic data is recorded in the records.

It has been commercial practice in the past to record alphabetic data by combinations of two perforations placed in the twelve index-point positions of a conventional Hollerith-type record card. This type of record card is divided into a certain number of vertical columns, usually 45 or 80, each containing twelve index-point positions and each letter of the alphabet is designated in each column by a perforation in the 0, 11, or 12 positions, commonly called the zone perforations or positions and a perforation in one of the 1 to 9 index-point positions, called the numerical holes or positions.

The usual code by means of which alphabetical data is recorded is given below:

Table I .--The Alphabetical Code 2 E 12, 5 P-11, 1 F-iz, 6 Q-n, s 12, r1 n n, 9 H iz, s s-o, 2 1-12, 9 'r-o, 3 .1 -11, 1 U-o, 4 K-11,2 v o, 5 L-11, 3 w-o, s ivi- 11, 4 X-o, 7 N-n, 5 Yeo, s ca -11, c z 0, 9 n c In order to compare the numerical data, it is customary to provide electrical sensing brushes which traverse each record column and these brushes, by reaching through the numerical perforations placed in the 1 to 9 positions, close circuits which, in the above patent, set up various comparing circuits, enabling a comparison to be made of the numerical data on two records.

In order tor` compare alphabetical data by means of the machine disclosed in the above patent it has been the practice to use two columns on the record card for recording each character of the alphabetical data, placing the zone holes in one of these columns and the numerical holes in the others. Thus alternate columns are devoted to reception of zone holes and numerical holes, respectively. By this expedient it is possible to use the machine of the above patent to compare alphabetical data as if it were numerical data. In order to effect this result the 0, 11, 12 zone holes are connected into equivalents in numerical index-point positions and the brushes for the columns containing the zone holes are plugged to alternate orders or positions of the comparing mechanisms so that the value of the numerical portion of the code for any character is entered into one position of the comparing unit and the connected value of the associated zone hole is entered into the next higher order of the comparing unit. Thus a 12 hole might be recorded as a 6, for example; an 11 hole as a 7; and a 0 hole as an 8, the particular group of holes selected not being important so long as they occur in the same order in the 1 to 9 positions, and have the same rela.- tive sequence meaning, as the zone holes ordinarily appear in the 0, 11, and l2 positions of the conventional alphabetical card. rThe following table shows how this may be done Table II A-G, 1 D-6, 4 Y

This expedient, while it enables alphabetical cards to be compared, is very undesirable for the reason that it greatly reduces the capacity of the commercial record card which is insuiiicient, as it is, under many conditions, to record all of the data that it may be desired to record in one card and the trend has been toward increasing the capacity of the card merely to increase its capabilityfor receiving a greater amount of numerical data. The main reason why the capacity ofthe card is greatly reduced is because the recording of names alone requires a very large eld onY the card, sometimes as many as twenty or thirty columns may be required to provide suiiicient capacity to take care of most common long names and the differentiating initials. When it is borne in mind 'that this must be doubledV in the card to provide the additiona1 columns for recording the translated zone holes it will be appreciated that even an 80column card will have very little capacity left forV recording numerical data. vOften when the cards are punched alphabetically by the more conventional way of using only one column foreach possible character, as in Table I, there stillV is insuicient capacity in a great many cases.

It, therefore, is the object of the present invention to providey Ya comparing mechanism which obviates thel use of Vdouble columns and thereby'enables the capacity of thecard to be used to themaximum possible extent.

Other objects of the inventionl will be pointed out in the following description and Vclaims and illustrated in-the accompanying drawings, which disclose, by way of` example, the principle of the invention and the Abest mode; which has been contemplated, of applying that principle.

. In the drawings:

Figs. 1A to 1E together comprise a wiring diagram of the machine. i

Fig. l2 is a vertical section throughthe right hand portion of the machine containing the primary and secondary feeding mechanisms and the record distributing mechanism.

I Figs. 3A and 3B together comprise a timing chart showing the electrical and mechanical timing of the machine respectively.

Fig. e consists of a plugboard chart showing how the machine is plugged for a simple opera tion in-which the cards are to be merged in accordance with their alphabetic sequence.

-It will-be noted byreference to rTable I that the alphabet is divided into three major sequence groups differentiated by the zone holes12, 11, and 0, of which the group Ato I, involving combinations of the 1 to 9 holes with the 12 hole is rst in sequence and the-group S to Z, involving the hole and the 2 to 9 holes, is last in sequence.

The usual order of v`sensing of the index-point positions on the card begins with the 9 position and traverses the card to the 0 position then traverses the zone index-point positions infth'e order 0, 11, and 12the sensing of the zone posi:

4 tions being inverse to the numerical significance' of the holes in the 0 to 9 positions.

Since the zonal sequence or zonal grouping of the character agrees in respect to the traversing of the record column by a sensing brush to the sequence within the group as determined by the 1 to 9 positions, it is possible to recode the alphabet in the manner disclosed in Table 1I in which the 0, 11, and 12 holes have been given the arbitrary values 8, 7, and 6, respectively. Thus the letter A might be considered as equivalent to a 6 hole and a l hole, the letter J as a 7 h'ol'e and the 1 hole, and S an 8 hole and a 2-hole. In other words, it is possible to consider these three letters as the numbers 6l, 71, and 82, respectively for purposes of comparison by entering these letters in the comparing units by making use of two denominations of the comparing unit.

In order to male use of this principle, the machine disclosed in the above patent isprovided with three sets of auxiliary sensing brushes which are designated SAB, PABI, and PABZ `in Figs. 1A, 1B,'and 2 of the drawings and identified as the secondary alphabetic brushes, the 'nrst primary alphabetic brushes, and the second primary alphabetic brushes, respectively. These brushes are associated with the brushes `SB,PBI, and PB2, respectively, which are retained in the :.nachine as in the above patent and aresimilarly designated in Figs. 1A, 1B, and 2. These brushes are structurally identical with the brushes SB, PBL and PBR but are located, with their companion contact rolls SACR, PACRI, and PACRZ, approximately in the relative positions occupied by the feed rollers E84, 191 of the above 'patent whereby, for example, the secondary alphabetic brushes SAB sense the 0, 11, and 12 index-point positions at about the time the main'secondary brushes SB are sensing the 8,' 7, and 6 positions, respectively.

It is thus possible to electrically recode or translate the usual 12, 11, and 0 holes into 8, 7, and 6`impulses, respectively, 'and thereby enter their relative group sequence values in the comparing mechanism during the period in which the l to 9 positions are sensed. In other words, if a card is punched with a 12 hole, the 12 hole will be sensed by a main brush SAB, for example, as Vif such hole were punched in the 6 position of the card column, and similarly at the other extreme a 0 hole will be treated as if it were an 8 holeand registered in an order or position of the comparing unit as an 8.

At' the same time the zone holes are being sensed and entered in the various orders or positi'onsof the comparing mechanism in this manner, the 'numerical holes will likewise be sensed and entered in other order of the comparing mechanism so that the net effect, for example, of 'sensing'the 12, 1 hole combination designating A will be to enter such combination' in two adjacent denominational orders of the comparing mechanism as the'number 61. Thus aname like 'Smitb, for example, requiring 've' columns on the record card when the ordinary method of using two holes per column'is used, would be translated by the auxiliary alphabetic brushes into the ten-digitnumber 82-74-'69l-83- 68, requiring ten orders or positions ofthe comparing unit for its reception. The comparing unit will Vfunction exactly like it would for any other multidigit number and, in comparing the name Smith with another name similarly recoded by the effectoffthe brushes SAB, lFABklv and PAB2, the alphabetic data will be treated like a number with a large number of digits.

This, of course, reduces the capacity of the comparing mechanism by half, but in many cases, involving simple operations, it is possible to offset this by using both comparing units of the machine of the patent in series to provide sixteen columns capacity for alphabetic comparing; the comparing units of the commercial machine ordinarily comprising sixteen orders or positions. However, this loss of comparing capacity is a relatively minor evil in comparison with the necessity of using thirty-two columns of the record card under the former expedient of punching the zone holes in columns interspersed with the numerical columns since the capacity of the comparing mechanism may be made greater but it is not possible to increase the capacity of cards already punched.

Fig. 4 shows how the machine is plugged for a very simple merging operation equivalent to the one disclosed in Fig. 20d of the above patent involving an alphabetic field-of five columns. The plug wires for the 2nd, 3rd, and 4th columns have been omitted to make it easier to `see the method of plugging and avoid confusion of lines; Since the functioning of the machine in the present case under the alphabetic comparing control will be identical with the functioning of the machine in the above patent as described with reference to Fig. 20d therein, only the additional circuts involved in entering the alphabetic zone designation in the comparing unit and their effect will be described herein in detail.

It will be noted from Fig. 4 that the plug wires for the main brushes SB, PBI, and FB2 are plugged in the same manner as in the above patent but to alternate orders of the comparing units beginning with the fifteenth and terminating with the seventh, while the auxiliary or zone brushes SAB, PABI, and PAB2 for columns 1 to 5 are plugged to positions 16, 14, 12, 10, and 8, respectively, it being necessary for any one card column to plug the orders of the comparing mechanism in such a manner that the zone holes for such column will be entered in as numbers the next higher order of the comparing unit to the one in which the numerical portion of the code for the same column is entered. Insofar as the numerical portionof the code is concerned, the machine will function exactly as in the above patent in comparing a single number, to enter the numerical portions in the ifteenth, rthirteenth, eleventh, ninth, and seventh orders or positions of the comparing mechanism. The

corresponding zone holes, however, will be en-Y tered in the sixteenth, fourteenth, twelfth, tenth, and eighth positions. Thus, if the name Smit in card columns 1 to 5 is to be compared with some other name, the designations for S, comprising a 2 hole in combination with a O hole, and transe lated by the column 1 brush SAB, for example, into an 8 hole, will be entered in the sixteenth and fifteenth orders of the comparing unit as if it were the number 82. The circuits for the numerical entry are set up in exactly the same fashion as in the above patent and a typical one through a brush SB may be traced in Fig. 1A as follows: Line wire WI, Lthe fifteenth order comparing magnet SMI, the plug socket PS4, the plug Wire, plug socket PSI, brush SB, the secondary contact roll SCR, common brush SCB, contacts RESA which are closed when the machine is running, the circuit breakersCB3CB4, CB2, CBI, and contacts CRB, to linewire W2.

This causes the sector associated with the magnet SMI to assume the numerical position 2l andV circuitV breakers CBI to CB and contacts CR3, Y

to the line wire WI. By these two circuits the letter S is entered in the comparing unit as 82 since, at the time the main brush SB is sensing the 8 index-point position, the brush SAB will be sensing the 0 position and the effect of the 0 hole will be translated into the comparing unit as at 8 but it will be in the next higher order to the 2 which is entered under control of the main brush SB.

It will be understood, of course, that the 82 will be entered in the secondary half of the selector unit. On the other side of the comparing unit there might be entered in a similar fashion some other alphabetic combination as,'for example, 83 representing the letter T, Table II. If such were the case, the two columns compared under such conditions would cause the switching mechanism for the fifteenth order of the selector unit to become set to the low secondary condition, as in simple numerical comparison, therebyV selecting the relay R22 or any function plugged to the plug socket PS3'I. With the plug-ging arrange-l ment shown in Fig. 4 using the basic setup conm trols and involving only simple merging of records, it would signify that the secondary card designated Smith is lower in sequence than the card designated with the T with the result that the card designated S would be fed first, irre-r spective of the condition of the lower orders of the comparing unit because the sixteenth posi` tion or highest denominational order of the comparing unit will dominate in this case over the lower orders in the well known way and cause the card designated S to be fed iirst. The contacts CRI2 time the auxiliary alphabetic brushes SAB, PABI, and PABZ to restrict the period in which they are operative to sense the card to the interval when the main brushes SB, PBI, and FB2 are sensing the 8, 7, and 6 positions on the cards. This prevents the even numbered orders of the comparing unit, which in the present case are devoted to receiving the translated zone representations, from responding to numerical desig-l nations at times in the cycle when the 9 to 1 positions are passing the auxiliary brushes. It is not necessary to similarly time the main brushes SB, PBI, PE2 because theY energization of the numerical comparing magnets between 0,11, and 12 in the cycle has no serious effect on the electromechanical comparing mechanism.

The comparing mechanisms function in exactly the same way as in the above patent when comparing simple alphabetic data entered therein exactly as ir it were a large number. Thus Smith would be compared with Snell by recoding these names as 8274698368 and 8275657373 and treating them purely as numbers.

In the drawings the plugboard is shown Vasproviding for only sixteen auxiliary brushes for columns 1 to 16 of the card making it necessary torecord the alphabetic data in columnsv 1 to 16L numerical data, treating the In this case the 5 for Snell 1 and the 4 for Smith in the thirteenth orders of Thisfis: common practice.` in the; artv but it israpf. parentth'at the machine may. be equipped. with a greater .number vof:` auxiliary brushesory the brushes may be'located inalignmentwith any dee.
